A lot of music— especially metal— is known for having lyrics that sound cool and evoke a specific feeling but that don't actually have any coherence. Creek Mary's Tears tells a specific message; but for the most part Nightwish's lyrics don't.
I feel like it's wasted potential. After listening to Two for Tragedy over and over today, I feel like this song could have been way better if it actually told a story instead of just sounded nice. I understand the principle that having vague lyrics can leave songs open to interpretation, but I feel like a lot of these— like Nightwish— don't really have the right words to provide a lot of room for meaningful interpretation.
I wish more of their lyrics made night. Fixed it for you.
